Wireless Charging Coils


A wireless charging coil is something that can be installed into an area or device for the purpose of receiving a wireless signal that will be used to charge the device.
How does it all work?
The coil is optimised for inductive charging, also known as wireless charging. This will allow you to charge your device wirelessly (only compatible with a devices’ battery that will accept this type of charging). Through the use of the electromagnetic field between two devices, the energy is transferred. There are two functions, one is the transmitter the other is the receiver with one beaming the field and the other receiving it.
Features and benefits:
• Easy to install and maintain
• Great advantage of being able to wireless charge your devices – no wires!
• Inductive charging – tight power transfers of a few meters, has the strongest power efficiency
• Resonant modes – Signal is lower but has a longer ranger for charging capabilities.
Where might I use one?
• In your home, if you already have too many cables and wires
• For your workplace, great for your employees
• In your business, provide wireless charging for your customers benefit
